My name is Sandra and I have the same problem that you are discussing here. I have managed to upload the Uk_Region svg and corrected in the 'Definition' and the map is still not showing. My data is on student applications in UK where the student from each region need to be counted/summed. Mars tailed off without discribing what he did in the js. The first line has the word "example" could this be the problem. Also have the problem that my SVG world map is not hooking up with the uploaded student data at internation level. The map appears but then it does not connect with the data (used world map in the SVG file). I am most grateful for any assistant you can provide me.
